Frequently Asked
What's the weather like on Ben Lomond in summer?
Summer on Ben Lomond offers the longest daylight and the warmest summits — typically 8-16°C at 974m in June-August. Rain is still common (this is Britain), cloud can still sit on the tops, and thunderstorms can build on hot afternoons. Check the hourly forecast and be off the summit by early evening if storms are forecast.
When is the best month for Ben Lomond?
June often wins: the longest days (16+ hours of daylight), the most settled high pressure, and midges not yet at their worst. July and August are warmest but mean midges, crowds and higher thunderstorm risk. September can be spectacular — clear air, golden light, and the first snow dusting on the highest tops.
Are there midges on Ben Lomond?
Scottish and Irish midges are worst in still air below 400m — so lower slopes and sheltered corries of Ben Lomond between mid-June and mid-September. Wind over 7 mph keeps them off. Carry repellent (Smidge works best), and consider a head net for camp stops. English and Welsh hills have fewer midges.
Do I need sun protection on Ben Lomond?
Yes — UV is stronger at altitude and glare off cloud is surprising. Sun cream, sunglasses and a brimmed hat. The hillandglen.com forecast shows the hourly UV index for the summit.
